Hi, I'm pretty new to SPSS but I have a project I'd like to work on, would anybody be able to advise me on which tests to run so I can look for an instructional video? I've got my beekeeping records from this year and a few colleges' sheets. It has data about how much honey we've had produced...
2. ### Sensitivity & Specificity Analysis

Hello, I have carried out sensitivity and specificity analysis on two neuropsychological tests to determine their utility in detecting impairment (mild cognitive impairment/Alzheimer's disease) relative to controls. The tests show opposite profiles: one has a sensitivity of 83.3% and...
3. ### What is is the meaning of this p-value ?

i am trying to perform cox regression on survival data of tumor patients with the covariate "resection status". Patients had either biopsy (=0), partial resection(=1) or total resection of the tumor (=2). I have trouble understanding the following: "total resection" (=2) is the reference value...
4. ### Time series analysis - residuals arent stationary

Hey everyone, i'm struggling with modelling some times series to get residuals with white noise characteristics. I use SPSS for ARIMA modelling and exponential smoothing and Gretl for stationary testing with the Augmented-Dickey-Fuller and the KPSS-Test. My workflow: At first I use Gretl to...
5. ### LOGISTIC REGRESSION ASSUMPTIONS - linearity for categorical IV's

Hi! I am going through the assumption for a logistic regression but I am stuck on making sure the 'IV is linearly related to the log odds'. My DV is dichotomous and all of my IV's are categorical (some binary, others with multiple groups). I am struggling to test this assumption on my data as...
6. ### What analysis do I use best? (SPSS)

Hi all I'm doing research on pay in function of degree (master vs. doctorate) and gender (man vs. woman). My research consists of 1 dependent variable: salary (salary varies from 210 euro to 12.000 euro in absolute numbers) and 1 independent variable degree (master vs. doctorate) and 1...
7. ### KALPHA not working

Hi Everyone, Would you please help me understand why SPSS says "The first word in the line is not recognised as an SPSS statistics command" even though I have installed and activated the Hayes kalpha macro? I would appreciate if you can suggest possible ways on how I can fix this or any other...
8. ### SigmaPlot Boxplots

Hi all, New here and hoping someone might be able to help (with what is a potentially stupid/obvious question--so apologies if that is the case). I am trying to make some boxplots on SigmaPlot, however I have realized the calculation they use to compute the quartiles, as well as the whisker...
9. ### Can I use Hayes' PROCESS macro for full mediation research models?

Hi all, I got the advice to use Hayes' PROCESS macro through SPSS for my research model, specifically model 4 and model 7. However, these models represent partial mediation, while my research model is full mediation. Hence, I was wondering whether I can use them for my analysis. If so, do I...
10. ### three-way mixed factor ANOVA

*** Apologies for cross-posting this message. I just thought that people who don't use SPSS may still be able to help. This is a question about within-subject factors in a three-way mixed factor ANOVA. I am terribly confused and I need some help. I am trying to run a three-way mixed factor...

I am conducting research on the effects of social media usage (frequency of checking and duration) on body image and self esteem n = 264. Every ANOVA is not significant :( however Boxplots have revealed a good number of outliers. When I removed 5 "moderate outliers" (between the mild and extreme...
12. ### How to analyse my data?

Hello, Im analysing my data for my thesis but i cant seem to figure out what analyses to conduct. I have coded miscommunication during a training. 5 day time trainings and 4 night time trainings. I used 5 codes to label the miscommunication. There were 3 rol's during the training which have...
13. ### Post Hoc Analysis

Hi, I am having trouble running a post-hoc analysis as I keep recieving the message: "Post hoc tests are not performed for EmpathyMean/AltruismMean because at least one group has fewer than two cases." I am trying to compare the means between two independent variables (Altruism & Empathy) and...
14. ### Problem with repeated-measures GLMM in SPSS for psycholinguistic study: Failure to converge

I'm trying to run a generalized linear mixed model in SPSS, with a continuous response variable (ResponseTime), SubjectID as a random factor, Items as a repeated measure, and five fixed factors: three categorical subject variables (Sex, Handedness, Familial Handedness) and two categorical item...
15. ### How to find the trend in binary time-series?

Hello everyone! I have an event that can happen with each of my patients (Y or N), collected over many years. Theses patients are independent of each other. I want to detect the trend taking into account the binary nature of my variable but also the number of cases per year. For example, I...
16. ### Testing for similarity between countries

For my thesis, I am looking at the effect of environmental controversies on the profitability of Chinese and European firms. As part of my exploratory analysis, I have to check whether or not the European countries are similar enough to consider them as 1 group. I collected data on economic...
17. ### Reporting Fisher's exact test (chi squared test)

Hello, I have conducted some chi squared tests but because the assumption for "minimum expected cell frequency" was violated, I'm using the value for Fisher's exact. However, I don't know how I can report the output. For example, the normal chi squared would be reported like this: χ2 (1...
18. ### MANOVA or repeated measures anova or ANCOVA?

Hello! For my thesis I want to compare 3 training groups (2 different types of training and 1 control group) to see the influence on mindfulness-skills and exhaustion level (so 1 IV- type of training- and 2 DV). All the participants get a pre and post test. I'm doing the analysis in SPSS, but...
19. ### Reliability Test - Cronbach

Hello, Through my quasi-experiment in math classroom, I have made pre and post-exams. Each exam had 3-4 open-ended questions (not MCQ). Each question had a different score. Each exam is summed up over 10. I was asked to do the reliability test using spss for each exam. The question is, should...
20. ### Significant Friedman's test but non-significant post-hoc tests

Hello, I am running a Friedman's test because I want to see if there is any difference in my participants' scores across 4 time-points. My sample is n=51. I ran the test and it revealed a statistically significant difference (p = 0.29). Then I conducted post hoc tests to see where the...
